Not content to sit back and enjoy the breeze coming off its ka-ching-ing runaway hitThe Avengers, Marvel announced today that it's in negotiations with Mads Mikkelsen to star opposite Chris Hemsworth in Thor 2. Mikkelsen, who plays blood-weeping Bond villain Le Chiffre in Casino Royale, will join Tom Hiddleston's Loki in the Norse villain's circle. No news yet on Mikkelsen's character—although Surtr, the fire-sword-wielding giant, is still available.
